No, it would not be nice not to deal with everything. For something to be nice, you need a live person who appreciates the nice situation and takes pleasure in it. If you remove yourself from life, there won't be anybody to enjoy how nice the situation is. 'Nice' is a matter of perception, and perception requires a live human being.

It is good that you take prenatal vitamins, but they probably do not contain that much iron and vitamin D, and a deficiency in those can contribute as a physical cause of depression. See a family physician for a blood panel to rule that out. Thyroid also needs. To be checked.
